When shopping for drapers online, the first thing you should note that color seen on your monitor may be different from what you are looking for (stoff dronning). It would be much better if you ask for a sample of the draper fabric; you have chosen or get print of the picture of the fabric.
Color matching is the primary thing and to find matching color draper for your home or office, you need to do some homework. Getting color print of the picture of drapers that you are viewing on your monitor is a good idea to determine which colors matches with your home decor.
Next thing is measurement. You need to know the length and breadth of the draper; you need to cover the windows and doors in your home (https://www.stoffdronning.no/categories/symaskiner1). The cost of a draper is determined by measuring its shape and size.
You can give approximate measurement but it should be larger than the actual measurement. If wish, you can ask a draper designer to help. If you are doing it on your own then you need to take the measurement on your own. Many homeowners design their drapers on their own but they know how to measure the area to be covered.
Designing curtains is an art. It is quite different from sewing clothes. But you can take drapers as clothes for your home. In this way, you can find a better design. Draw a design on paper and see how it looks like.
The curtain fabric, you choose, plays a leading role in giving your home the look, you are dreaming of. Cotton is the preferred fabric but you should look all the fabrics available in the market. Read about each fabric and determine its usability. If you like then you can get a couple of drapers in different fabrics for a change.
